L-Glutamine – an amino acid that belongs to the basic building block of proteins, which form muscle mass

L-Glutamine is one of the most abundant amino acids in the human body. It primarily serves as a fundamental building block for proteins, which are used for muscle mass development. It accounts for approximately 50-60% of all amino acids found in the muscles. L-glutamine also serves as a source of energy for the cells of the immune system and the intestinal mucosa, making it often mentioned in relation to immunity and digestion. However, the functions of glutamine in the body go beyond – it also acts as a precursor to an antioxidant known as glutathione.


The amino acid L-glutamine is referred to as conditionally essential. This means that the body can produce it on its own to some extent. However, there are situations where this natural rate of production may not suffice. This happens, for example, when engaging in high-intensity or endurance training, during periods of stress or while ill. In such cases, dietary intake and supplements can help in replenishing this substance.


The properties of L-Glutamine thus make it ideal for all athletes and active people. Apart from strength athletes, it will also come in handy to endurance athletes, especially after prolonged performances. On top of that, it has a purely plant-based ingredient profile, which makes it also suitable for vegans.
